There seems to be a paradox here. Sustainability is not synonymous with absence of change. For new life to have room; for new inventions to have room - old life must die and must be recycled, and old products or suoerfluous products need to be destroyed and recycled.

One strategy for killing bacteria - and some cancer cells - centers around filling the cell with useless protein material by (for bacteria) making defective proteins, or (for cancer cells) inhibiting breakdown of protein material. So the target cell suffocates in its own unrecycled waste. Society and cells - this time I think I found a common mechanism.
